v absorbent-s said base with u. wardly-extending arms (1 for the pur ose oi guiding the reciprocating eet support now to be described. The support for the pile of absorbent leaves is here shown as comprising a rectangular framehaving the side members E E, connected by the end members e e. The side members E near their forward ends are provided with studs 6 which operate in slots. e formed in theupper ends of levers ,F, pivoted at f to the ears f secured to the base D. One of said levers F is provided with an angular extension 7' said extension, with the ever F, forming a bell-crank, and the extremity of saidextension) being pivoted-at f to a vertically-reciprocatmg bar f the upper end whereof is pivoted at f to the face of the pinion a. As will be seen, the rotation of said pinionimparts vertical reciprocation to. the bar f thereby operating said bell-crank lever and, imparting a horizontally-oscillating movement tothe supporting-frame E.

Therear paper-guide C is provided with oflset lips 0 forming a seat for the rearward end of'the frame E between said and the upwardly-extending members of said guide. As befs'een, therefore, said frame is supported in a horizontal plane at its forward end by the, lovers F and at its rearward endby said rear paper-guide and the brackets '0 whereby said guide is supported.

' the pins G intoregistry from the bottom is ings the sheets to be printed 11 on are fed. successively to'the neostyle-an the drum G G designate pins carried by and 'ro'ecting inward y from the side members-E oi the reciproeating'frame.-9n these pins (see Fi' 4) the absorbent sheets H are $11 porte said absorbent sheets'H are provided with notches hk at each side ed e, the notches h hbein' nearer to theiorwar end ofthe sheet than are notches h h are to the rearward end oi the sheet. As-a result, although a plurality of' the sheets may be notched at a time, they may before introduction into the machine be alternately reversed, so that only the'n'otches of alternate sheets shall be in register, as illustrated in Fi 4..

The pile of sheets notche as. herein describedis in operation arranged upon the pins G ofthe reciprocating carrier and the owermostsheet released when said carrier has been moved a sufiicien't distance to bring the notches in The release of the next'sheet' precluded, however, since its notches are not'in registry with those' of the lowermost'she'et. To release that sheet, therefore, a return movement of thecarriage is necessary, so as to bring the pins G into registry with the differently-- 'placednotchesinthatsheet.

g In the mechanism illustrated in the drawthat sheet.

'thereof'rotated, this movement causing a clprocating movement of the absorbent: sheet supportmg carriage corresponding with absorbent sheets may be different ing with a slot the movement of the drum. As the sheets are printed upon by the stencil on the periphery of the drum, they are fed between such drum and the impression-roller directly underlying the same into the paper-tray I. As the printed sheet comes to a rest in such tray, the pins G are moved to a point where they register with the notches in the lowermost sheet of the pile of absorbent sheets,

vwhereby such lowermost sheet is released and permitted to fall directly upon the upturned face of'the printed sheet, and this 0 eration may be continued indefinitely, t 6 result being that between each two printed sheets has been inter osed one of the absorbent sheets releas in the manner herein stated. It is not essential that a horizontally-reciprocating carriage be employed, as the invention may to equal advantage be embodied in a construction wherein the lpile of y arranged-as, for instance, at an angle relativey to the horizontal. Such a construction is illustrated in Figs. 6 and 7, wherein the sheet pile may be arranged on the under si' e ofi an oblique carrier A releasing device L may be employed to successively re leasethe absorbent sheets, the same having angular arms Z, provided at their ends with studs or sheaves Z, which as the device is moved relatively to the pile register successively with notches formed in the edges of the absorbent sheets; Where such areleasing device is employed, it ma be actuatedin any suitable manneras, or instance, by means-of apin Z, carried by the pinion Z of the 'duplicat'in a paratus, :such pin coact- 5, ormed in an arm Z", to the end of which said releasing device may be secured. With this construction, aswith that above described, an absorbent sheet is released as a printed sheet is fed into the papertray, so that the result of the duplicating operation shall be a ile of printed sheets interleaved with absorhent sheets.
